Abstract

A method for processing in-device coexistence configuration information, apparatus and system. The method includes: notifying, by a source base station to a target base station, first in-device coexistence configuration information configured by the source base station for terminal equipment, when handover from the source base station to the target base station occurs in the terminal equipment. In this way, the source base station may notify the first in-device coexistence configuration information configured by it for the terminal equipment to the target base station; the target base station receives the first in-device coexistence configuration information, determines whether to configure the terminal equipment with in-device coexistence configuration information, and then notifies the source base station of related configuration information via a handover command. Wherein, when handover occurs in the terminal equipment, the in-device coexistence configuration information may be processed effectively.

Claims

1. A terminal equipment which is able to perform communication with a base station in a first system and perform communication with another device in a second system different from the first system, comprising:

a processing unit configured to release in-device coexistence configuration information configured, upon the terminal equipment initiates RRC connection reestablishment;

the in-device coexistence configuration information comprises the configuration information on whether the terminal equipment is permitted to transmit in-device coexistence indication to the base station and the configuration information to control the terminal equipment to perform autonomous denial of uplink signal transmission of the first system;

not transmit in-device coexistence indication by the terminal equipment to a new base station, when connection between the terminal equipment and the new base station is reestablished and the terminal equipment does not receive in-device coexistence configuration information containing first configuration information transmitted by the new base station, wherein the first configuration information refers to configuration information configured by the new base station to indicate a permission to transmit in-device coexistence indication to the new base station by the terminal equipment.
